The collector is operated at constant temperature ϑm (mean of in- and outlet temperatures). The calculation of the annual collector
performance is performed with the official Solar Keymark spreadsheet tool Scenocalc Ver. 5.01 (March 2016). A detailed description
of the calculations is available at www.solarkeymark.org/scenocal

811/2013 as collector efficiency of the solar collector at a
temperature difference between the solar collector and the
surrounding air of 40 K and a global solar irradiance of 1000 W/m²
,
expressed in % and rounded to the nearest integer. Deviating fro

the regulation η col is based on reference area (A sol ) which is
aperture area for values according to EN 12975-2 or gross area for
ISO 9806:2013

EN 12975-2 or gross area for ISO 9806. Consistent data sets for
either aperture or gross area can be used in calculations like in the
regulation 811 and 812 and simulation programs
